New Features

Here, we are going to highlight the new features that have been introduced in this release.

KubeDB managed Cassandra Backup/Restore

KubeDB now supports backup and restore for Cassandra databases using KubeStash and the Medusa plugin. This enables reliable data protection with cloud storage backends (e.g., S3, GCS).

Backup and Restore Workflow

• BackupStorage: Specifies the cloud storage backend.
• RetentionPolicy: Defines how long backup data is retained.
• Secrets: Stores backend access credentials.
• BackupConfiguration: Configures the target database, backend, and addon.
• RestoreSession: Restores data from a specified snapshot.

In below given the example of a BackupConfiguration for a Cassandra database

apiVersion: core.kubestash.com/v1alpha1
kind: BackupConfiguration
metadata:
  name: cass-backup
  namespace: default
spec:
  target:
    apiGroup: kubedb.com
    kind: Cassandra
    namespace: default
    name: cass-sample
---
      addon:
        name: cassandra-addon
        tasks:
          - name: logical-backup
        jobTemplate:
          spec:
            serviceAccountName: cluster-resource-reader

And for Cassandra database below is the example of a RestoreSession:

apiVersion: core.kubestash.com/v1alpha1
kind: RestoreSession
metadata:
  name: restore-cas
  namespace: default
spec:
  target:
    apiGroup: kubedb.com
    kind: Cassandra
    namespace: default
    name: cass-sample
---
  addon:
    name: cassandra-addon
    tasks:
      - name: logical-backup-restore
    jobTemplate:
      spec:
        serviceAccountName: cluster-resource-reader

Introduce Workload Manifest Backup/Restore along with RBAC resources

KubeStash now supports backing up and restoring Kubernetes workload manifests, including associated RBAC resources such as Role, RoleBinding, ClusterRole, and ClusterRoleBinding. This enhancement enables users to capture not just application data but also the complete configuration of workloads for comprehensive disaster recovery.

Here is an example of BackupConfiguration:

apiVersion: core.kubestash.com/v1alpha1
kind: BackupConfiguration
---
sessions:
  - name: workload-backup
    addon:
      name: workload-addon
      tasks:
        - name: manifest-backup
          params:
            includeRBACResources: "true"
      jobTemplate:
        spec:
          serviceAccountName: cluster-resource-reader

Here,

• Set includeRBACResources: "true" to include RBAC resources in the backup.
• A custom serviceAccountName with appropriate cluster-level RBAC permissions is required for accessing these resources.

Here is an example of RestoreSession:

apiVersion: core.kubestash.com/v1alpha1
kind: RestoreSession
---
addon:
  name: workload-addon
  tasks:
    - name: manifest-restore
      params:
        includeRBACResources: "true"
        overrideResources: "true"
  jobTemplate:
    spec:
      serviceAccountName: cluster-resource-reader

Here,

• includeRBACResources: "true" restores the RBAC resources associated with the workloads.
• overrideResources: "true" ensures existing resources in the cluster are replaced with the restored versions.

By default, both includeRBACResources and overrideResources are set to false. Enable them explicitly if needed for your use case.

Improvements & Bug Fixes

Improved Pod Discovery for Deployment Backup/Restore

Previously, the system assumed that each Deployment would have only one associated ReplicaSet, which is not always true. We’ve updated the logic to identify the most recent ReplicaSet to accurately locate the active Pod during backup and restore operations.

Fixed Workload-Only Manifest Backup/Restore

Resolved an issue where backups and restores targeting only workload manifests were not functioning correctly. This fix ensures reliable handling of workload-only manifest operations.
